I recently changed my Netflix subscriptions to the xfinity bundle. Even though I am paying the extra $3.00 a month I lost Atmos on all my streaming platforms. Before the billing change Atmos would stream off the x 1 boxes, my Sony Bravia tv app and Roku Ultra. Now all I get is Dolby 5.1 on all devices. I called Netflix and xfinity twice. They all insist I don’t have the settings correct. I did not change any settings and triple check them all. I have been in to home theater since 1994. I am pretty confident I didn’t change a setting simultaneously on 4 devices at the same time and missed it.
how does your sound bar receive the audio from the set top box?

It’s not a sound bar. I have 2 AVR receivers. 1 in my basement, 1 in my living room. The both have a HDMI cable going directly in to the receiver and another one out to the tv.
try setting the x1 box to expert. atmos is just a text file (in ascii) sent in a stream much like closed captions
Check your Netflix subscription tier. You should be on the Premium tier if you're going to stream in 4K Ultra HD, HDR, or Dolby Atmos.. You're probably on the Standard tier.
Netflix supports streaming with Dolby Atmos audio on select titles.
What do I need to stream with Dolby Atmos audio?
A Dolby Atmos-capable audio system.
A plan that supports streaming in Ultra HD. You can check which plan you’re currently on at netflix.com/ChangePlan
A Netflix-capable device with Dolby Atmos support
Streaming quality set to High or Auto. More information about video quality settings can be found in our Playback Settings article.
It's a Netflix issue then, since even your Roku is affected and not just the X1 boxes. Tried logging off all the devices and log back on again.?
